Support Units（Page2）

Support units are special parts for bearings used in a set together with a ball screw. Support units come in various shapes, such as square, round and round 2-surface chamfered. There are also 2 different types—models used at the fixed side and models used at the support side. Support units attach to the fixed side and support side of a screw shaft, enabling the screw shaft to be mounted in the correct position. A bearing integrated into the body of the support unit enables stable shaft rotation. Support units are available with various types of bearings, sizes, shapes and surface treatments. Models for various applications, operating environments and mounting spaces can be selected. Support units can be mounted in equipment as-is, with no need for additional processes or machining.
